Patent JP-H0775379-A (JP)
Title: Voltage-type inverter device
Inventor: KUROIWA AKIHIKO
IPC: H02P27/06
Filed: 1993-09-07
Abstract: PURPOSE:To stably control speed even in a transition state where a frequency reference or a load rapidly changes exceeding a non-loaded state by separating a motor current into an effective current component and a reactive current component for detecting it and then compensating each independently for the frequency reference. CONSTITUTION:When load increases and a motor 14 decelerates and a slip frequency increases, torque current increases. The increase in the torque current is detected as an effective current which is outputted by an inverter 13 in a rotary coordinate conversion circuit 26 and then is subtracted from a frequency reference Vref as a stabilization signal where DC components are cut by an incomplete differentiation circuit 23a, thus stably controlling the generation torque of the motor 14 and the speed. On the other hand, when the voltage of a DC capacitor 12 increases, the output voltage of the inverter 13 increases and the excitation current of the motor 14 increases. The current is detected as the reactive current, a signal which is obtained by cutting DC components by an incomplete differentiation circuit 23 is used as a stabilization signal, and then the frequency reference Vref is increased for stabilizing a voltage control system.

Abstract: PURPOSE:To reduce deflection aberration and prevent deterioration of focus characteristics at peripheral parts of a face plate by disposing pairs of permanent magnets in the three-electron beam disposition direction and the direction forming an angle theta respectively with their polarity opposite to each other axially symmetrically to the center axis of a deflection device. CONSTITUTION:A pair of permanent magnets 28a, 28b, 50a, 50b, 60a-60d are disposed respectively at up, down, right and left positions and positions having a predetermined angle theta clockwise and counterclockwise horizontally to be axially symmetric to the center axis (Z-axis) of a deflection device 21 and to have opposite polarity to each other at a side end part 27 of an electron gun structural body of the deflection device 21. A pin-cushion shaped magnetic field is thus formed by the permanent magnets 28a, 28b, 50a, 50b, 60a-60d, so the magnetic field of the deflection device 21 compensates deflection aberration applied to an electron beam, and the focus characteristics at the peripheral parts of a face plate can be improved.

Title: Tone quality adjusting device
Inventor: CHIKAKI TAKAYUKI
IPC: H03G5/02
Filed: 1988-09-05
Abstract: PURPOSE:To reproduce acoustic waves which are more similar to actual sounds by selecting signals which are outside an audible band and are effective for tone quality adjustment out of the frequency components contained in an original signal system and against mixing the selected signals with the original signal system after protecting the signals from the loss and attenuation which take place in the circuit of an original signal transmitting system or intensifying the signals. CONSTITUTION:Resonance circuits F1 and F2 selectively act on specific frequencies effective for tone adjustment of the signals supplied from an amplifier A. An ultrasonic wave generator SP1 reproduces only the ultrasonic frequency selected by the circuit F1 in spots. Another ultrasonic wave generator SP2 also reproduces only the ultrasonic wave selected by the other circuit F2 in spots. The resonance circuits F1 and F2 and ultrasonic wave generators SP1 and SP2 respectively constitute by-pass circuits about signals of audible bands. By adding the specific frequencies in spots by means of the ultrasonic wave generators SP1 and SP2, the reproduced frequency band can be expanded partially to the area of several hundreds kHz and the tone quality can be made variable by effectively operating the interference phenomenon between frequencies of high-frequency bands generated by the ultrasonic wave generators SP1 and SP2.

IPC: H04N5/378
Filed: 1988-09-08
Abstract: PURPOSE:To reduce a fixed pattern noise and to improve picture quality by making incident a light quantity with low luminance and a light quantity with high luminance with the same storage time T1, and the light quantity with high luminance with at least one or more storage times T2,... shorter than the time T1 on a solid-state image pickup device, respectively. CONSTITUTION:The storage time of a solid-state image pickup element 7 is set, for example, at two kinds of times T1 and T2 as leaving two reference light sources as it is. Thereby, three kinds of incident light quantities (low luminance, intermediate luminance, and high luminance) can be obtained essentially, and the output voltages of them are stored in memories (101-103). Next, a movable mirror 5 is located at a position (c), then, an image pickup mode is set. Thereby, light from a visual field is made incident on the solidstate image pickup element 7 via a fixed mirror 4, the movable mirror 5, and a lens 6. Then, an arithmetic processing is performed by a formula set in advance by a digital signal processor DSP 13. In such a way, each image element can be taken out after being corrected to the same output voltage even when the incident light with the intermediate luminance is inputted, then, it can be displayed without generating an error.
